Integers

Signed types start with an i and unsigned types start with a u
isize and usize are architecture dependant (32-bit or 64-bit)
_ acts as a separator for numerical literals

let decimal: i32 = 1_000_000; // Equal to 1,000,000
let hex = 0xff;
let oct = 0o77;
let bin = 0b1111_0000;

Warning

Rust does not include integer overflow checks when compiling with the --release flag.
If over flow occurs, it performs two's complement wrapping^[1]
